I search a lot of questions and answers in SO. This is what i figure out. The result I want is map can zoom out to fit all/some annotations INCLUDE user's location.

The basic steps are:

Calculate the min lat/long
Calculate the max lat/long
Create CLLocation objects for these two points
Calculate distance between points
Create region using center point between points and distance converted to degrees

	import SwiftUI

	struct DropdownOption: Hashable {
	let key: String
	let value: String

	public static func == (lhs: DropdownOption, rhs: DropdownOption) -> Bool {
	return lhs.key == rhs.key
	}
	}
